“…Afterwards, the sheet with integrated micro-fibers can additionally be shaped through deep drawing [5]. In [6] the feasibility of combining forming and screen printing for the production of loadbearing sheet metal parts with integrated strain sensors is demonstrated. The developments described so far are at an early stage and not established in industrial production chains till now.…”

In metal forming a trend is observed towards increasing the performance of products by means of functional integration. One approach being pursued is the integration of electronic components. Multifunctional profiles with electrical conductors can transmit data and energy in addition to the mechanical function. They can be produced efficiently by roll forming. During the roll forming of multifunctional profiles wrinkles and cracks in the conductors may occur in the area of the contact of the rollers due to the contact normal stresses. In this paper, a design approach for multifunctional profiles preventing these failures in the tool contact area is presented and discussed on the basis of experimental and numerical investigations.

Purpose In 3D additive screen printing with constant snap-off, the inhomogeneous screen counterforce will influence the printing force and reduce the printing quality. The purpose of this paper is to study the relationship between scraper position, snap-off and screen counterforce and develop a variable snap-off curve for 3D additive screen printing to improve the printing quality. Design/methodology/approach An experiment was carried out; genetic algorithm (GA) optimization theoretical model, backpropagation neural network regression model and least square support vector machine regression model were established to study the relationship between scraper position, snap-off and screen counterforce. The absolute errors of counterforce of three models with the experiment results were less than 1.5 N, which was tolerated and the three models were considered valid. The comparison results showed that GA optimization theoretical model performed best. Findings The results suggest that GA optimization theoretical model performed best to represent the relationship, and it was used to develop a variable snap-off curve. With the variable snap-off curve in 3D additive screen printing, the inhomogeneous screen counterforce was weakened and the printing quality was improved. Originality/value In printing production, the variable snap-off curve in 3D additive screen printing helps improve the printing quality; this study is of prime importance to the 3D additive screen printing.

“…Due to increasing public, political and ecological requirements, such as decreased fuel consumption or less exhaust emissions, the significance of composite materials continually rises in the automotive sector. Furthermore, the importance in the field of consumer and multi-functional products is growing, too [1]. According to Vinson [2], composite materials can be categorized based on the adopted structural framework.…”

Experimental and analytical investigation of the force requirements in shear cutting of metal-polymer-metal composites

et al. 2017

View full text Add to dashboard Cite

The increasing demand for lightweight design requires the use of multi materials such as metal-polymermetal composites. These so-called sandwich panels offer a good stiffness-to-weight ratio. Production technologies like shear cutting have to be adapted for these materials. For a targeted adaption, a comprehensive knowledge about the cutting phases of the shear cutting process of sandwich panels is essential. Therefore, within this paper, the shear cutting process of sandwich panels is studied in detail. The conducted experimental studies indicate that the shear cutting process can be divided into five stages. Based on these findings, a new analytic model is introduced to predict the force displacement curves of sandwich panels. The quality of the new model is proven by comparison with existing analytic models for monolithic materials as well as with the experimental data.
